PAPERPFEEDING MACHINE.

specification of Letters Patent. Application filed July 30, 1913. Serial No. 781,908.

Patented May 26, 1914.

To all whom it may concern Be it known that 'I, EMIL JAcnNnnnG, a subject of the German Emperor, and reslding' at 107 Himrnelgeisterstrasse, Dusseldorf, Germany, have invented certain new and useful Improvements in Paper-FeedingMachines, of which thefollowing is a spcclfication.

The present invention relates to an arrangement for drawing off and displacing the single sheets on piles by means of belt conveyers-traveling beneath the said piles from the same the lowerfeed rollers.

According to the present invention a fr1ction clutch is provided in such an arrangement in the driving gear between the feed rollers and the roller of the belt conveyor, which clutch is locked by means of a finger arranged next to the feed rollers on the arrival of the sheet drawn off, so that the belt conveyor is stopped, although the driving gear continues to run, and no further sheet will be drawn 0H, until the said lock is disengaged;

V In the accompanying drawing Figures 1 and 2 the invention is exemplified in side elevations, whereas Fig. 3 is a plan of the same.

The pile of sheets a rests on the taut belt conveyers b, which are drivenby means of the rollers d. In the same level with these belts the air of feed rollers f is journaled, which is riven by means of the gear wheel g. This gear wheel 9 also engages with the gear wheel 71., which isloose on the shaft of the roller d, but is rigidly secured to the one member 2' of a friction clutch. This member of the friction clutch can revolve loose on the shaft of roller d, while the other membor /c of the clutch is keyed to this shaft.

Parallel to the rollers f a shaft on is jour naled, which carries an arm n, which proiects like a finger into notches in the two 'At the free end of shaft m is secured a lever,0, which has a hooked end 39 and a bar r extending obliquely upward, on .which a Weight 8 is highest position of which is limited by a stop If, engages during its descent between beyond its fitted. This lever p, the

the pins to, which are fitted in a circle on the disk 12 secured to the shaft of the rollers d. When there is no sheet between the rollers the weight 8 will press the finger it into the notches of the rollers f and lift thehook p from the gaps between the pins a (Fig. 1). The. drive by means of the gears g and h, by

which also the one member of the clutch a is.

revolved, will then also revolve the, clutch member 7:: and the roller (Z. The conveyor belts will thus be advanced, so that the lowermost sheet of the pile a is advanced to ward the feed rollers f. When, then, this sheet enters between the rollers f, its front edge strikes against the finger n and moves it, so that the weight is lifted and the hook p is lowered between the pins a (Fig. 2). The rotation of the disk '2; is therewith stopped, so that the two clutch members now lide on each other and the roller d with t e conveyer belts does not move. As soon as the sheet has passed through between the rollers f, the finger it again drops down and the hook p is raised, so that now the friction between the clutch members will again cause the roller cl to revolve and a fresh sheet to be advanced.

The pile is displaceabl arranged in the direction-of the conveyor sits on the top of the'machine. Its distance and the interval between the removal of two sheets ma. therefore be readily varied at will. The finger a may also be arranged on the other side of the feed rollers, where it will be lifted in the same manner. It is also possible to arrange the weight in such a manner,

that on the finger n being raised, it is lifted highest position, so that it then forces down the hook p. In this case the latteris again released by means of a lever or the like operated by the device to which the sheet is fed, and the weight is reversed.

I claim:

A paper feeding machine comprising a belt conveyer adapted to engage the bottom sheet of a sheet pile, a driving roller for said 'conveyer, a first clutch member and a pin disk fast on the driving roller-shaft, a notched feed roller arranged in advance of the belt conveyer, a second clutch member loose on the driving roller shaft and intergeared with said feed roller, an oscillable my signature in the presence of two witarm adtgpted to engageltheb feed rollller-notcgt nesses. and to e engaged b t1e ottom s eet, an 7 a an overbalanced levez' operatively connected EMIL JAGENERG 5 to said am, and adapted to engage the pin Witnesses:
